WILLIAMS, OF BRANFORD, CONNECTICUT, ASSIGNOR T MALLEABLE IRON FITTINGS COMPANY, OF BRAJNFORD, CONNECTICUT, A CORPORATION OF CO-N- N'ECTICUT ELECTRIC-RAILWAY EQUIPMENT Application filed February 6, 1930. Serial No. 426,321.

This invention relates to electric railway equipment, and has particular reference to the poles and cross arms or beams'which carry the conductor which supplies the electric current to the motors.

Heretofore the cross beams and poles have been secured together by means of clamping fixtures that necessitated the cutting of holes in the poles or beams for the passage of suitable bolts utilized in the clamping members, but while this has been found to be quite eiiicient, nevertheless it necessitated the cutting of the holes in the poles or beams after they had been distributed at the proper locations under the railway line, because the cross beams must be a certain distance above the railroad rails, and it would be impractical to determine beforehand the grade of successive mounts for the poles.

The object of the present invention is to secure the cross beams to the poles in such manner that it is entirely unnecessary to perforate the poles or beams in any manner, thereby preserving their full strength, and enabling fine adjustments to be made in loeating the cross beams at a required distance above the railroad rails.

Since the present invention has nothing whatever to do with the mounting of the poles the latter are shown in the drawings as broken away at the lower portions and it will therefore be understood that the poles may be mounted in any suitable manner.

Also, since the fixtures and their manner of application are precisely the same at both ends of the cross beam, the drawings only show the invention as applied to one end of a cross beam and the manner of securing it to a pole, and referring to these drawings Figure 1 is an elevation with the pole and cross beam broken away and showing the manner in which the invention is applied.

Figure 2 is a section at the line 22 of Figure 1.

Figure 3 is a section at the line 33 of Figure 2.

Figure 4: is a section at the line 14 of Figure 1.

Figure 5 is a detail view of the inner face of the pole as it appears when the pole fixtures are clamped thereto, and

Figure 6 is a detail end view of a cross arm with its fixtures secured thereto.

Similar numerals of reference denote like parts in the several figures of the drawing.

1 is a metal pole which is H-shape in cross section, although in some instances for lightor installations the pole may be of the I-beam structure which, however, is merely a modified form of the H-structure.

The poles are suitably mounted at the sides of the railway tracks with their broad surfaces 2 facing such tracks.

3 generally denotes similar clamping fixtures which have throughout their length channels 4 that slidably embrace the outer edges of the face 2, and are firmly clamped to these edges by means of bolts 5 passed through the fixtures 3 and nuts 6 driven on the ends of said bolts, and in this connection it will be observed that these bolts do not pass through any part of the pole 1.

The inner faces of these fixtures 3 have gates 7 extending horizontally, for the purpose presently to be explained, and from the upper and lowerends of these fixtures extend ears 8, while laterally from the sides of these fixtures extend horizontally disposed ears 9;

10 is a cross arm or beam of H-shape which extends between opposite poles and is se cured in the following manner 11 are fixtures which have formed therein channels 12, 12, that slidably embrace the opposite edges of the arm 10. The broad faces of the cross arm structure are horizontally disposed, and the fixtures 11 have upper and lower inward extensions "13, 14, throughout which the channels extend, the channels in the upper extensions embracing the side edges of the upper face of the arm 10, while the channels in the lower extension embrace the edges of the lower face of the arm 10.

The extensions 13, 14, have formed therewith open housings 15, 16, that extend respectively above and below the upper and lower faces of the cross arm 10, and through these, housings are passed bolts 17, 18, and nuts 19, 20, are driven on the ends of these bolts, whereby the fixtures 11 are firmly clamped to the cross arm 10.

Extending integrally from the rear faces of the clamping fixtures 11 are hook-like members 21 which are engaged through the gates 7 in the fixtures 3, so that it will be clear that the weight of the cross arm 10 is sustainedwby the fixtures 3.

" Exte-ndingfrom the upper andlower portions respectively at the inner ends of the clamping fixtures 11 are perforated ears 22 which when the cross arnilO is supported in the manner just described,' register with the ears 8 in the fixtures 8, and extending laterally from the fixtures ll are ears 23 which register with theliorizontal ears 9 in the fixtures 3, and these registering ears are clamped together by means of bolts 24, 25, respectively, and nuts 26' and 27 driven on theends of these bolts.

From the foregoing description it will be clear that the fixtures for the pole and cross arm have interengaging members, in order that the cross arm may be supported, and also that these fixtures are firmly clamped together in planes that are at right angles to each other, thereby establishing a very firm union between the poles and the cross arms.

More important still it will be noted that both the pole and the cross arm are imperforate. It will further be observed that the cross arm fixtures extend across the ends and across the upper and lower faces of the cross arm and this contributes greatly toward the balance of the structure and the firmness with which the fixtures are clamped to the cross arm and clamped to the pole fixtures.

The equipment heretofore described is lates to an installation for two or more tracks, but when there is but a single track there is only one set of poles or masts, and the usual mast armsare secured at one end of the pole or mast in precisely the same manner as that heretofore described, and therefore this invention is not limited in this respect.

It will be clear that, should it become necessary to raise or lower the railroad tracks, corresponding adjustments are readily made by relaxing the clamping bolts of the mast or pole fixtures and then sliding the latter along the pole to any desired location and finally rej-tightening 'the bolts.

What is claimed is 1. In an electric railway equipment, opposite imperforate metal poles H-shaped in cross section, fixtures slidably engaging said poles and having openings in their inner faces, means for clamping said fixtures to said poles, imperforate cross beans, fixtures that sheathe the ends and the top and bottom faces of said beams, projections from the end faces of these last named fixtures that engage within said openings whereby said beams are supported, means for clamping the beam'fixtures to the beams, and means for securing the beam fixtures to the pole fixtures.

2. An electric railway equipment, comprising imperforate opposite poles and imperforate cross: beams intermediate said poles, aset of fixtures secured to one of said poles and second set of fixtures secured to an end of said cross beam, one set of said fixtures carrying members, interengaging with the other set whereby the weight of the cross beams is sustained by the pole fixtures, and means for clamping the beam fixtures to the pole fixtures.

3. A construction as in claim 2 with the further provisionthat the pole fixtures comprise oppositely disposed clamping members that slidably embrace opposite edges of the pole and that have back portions extending across the inner face of the pole, each of which portions have openings therethrough, while the cross beam fixtures embrace thetop and bottom faces of the cross beam and extend across the ends of the latter, the end portions of the beam fixtures having hooklike members which are engaged through said openings whereby the cross beams are supported by the pole fixtures. v

4; A construction'as in claim 2 further dis-, tinguished in that the cross beam fixtures have open housings that extend respectively above-and below the top and bottom faces'of he cross beam,.and that bolts are passed through said housings and nuts driven on said bolts whereby the fixtures are clamped to the beam at points immediately above and below the latter; V

5. A construction as in claim 1 in which the poles and beam fixtures have vertical and horizontal registering ears through which bolts are passed andnuts driven thereon whereby said fixtures are clamped together in planes that are at right angles to each other.

In testimony whereof I afiix my signature hereto ROLLAND G. lVILLIAMS.
